Fix notebook cell selection bug (#402)

This fixes a bug that prevents getting focus to a text cell (effectively preventing editing) when the window height is small after double-clicking on a neighboring code cell.
The issue is that selecting a text cell is broken likely because there's a behavior change in MonacoEditor that keeps the focus on the code cell. The selection issue will probably be resolved when migrating the text cell to Monaco (which will acquire and keep focus the same way), but for now, this will disable the faulty code which doesn't appear to work anymore (presumably auto-scrolling to the cell).
